Description

Technical Field

[0001] The utility model relates to the technical field of metal piece processing, in particular to an automatic bending machine for metal pieces. Background Art

[0002] Metal bending machines are also known as press brakes. Press brake bending is a common metalworking technology used to bend metal sheets into desired shapes. It is essential in the metalworking industry and manufacturing. During the bending process, the metal sheet is placed on a press brake and can be bent into the desired angle and shape by applying pressure. The press brake usually consists of an upper punch and a lower die. The upper punch bends the metal sheet by applying downward pressure. This technology is widely used in the production of various products such as automotive parts, home appliances, building materials, etc.

[0003] When bending the metal plate that needs to be processed, it is usually necessary to hold one side of the metal plate manually and use a pressure bending machine to bend the other half. This process requires staying in one place for processing and requires manual adjustment of the front and rear folding positions of the metal plate, which is labor-intensive. In addition, during the stamping and bending process, the tail of the metal plate will curl up. If the worker is not careful, his hand may be scratched. Therefore, in response to the above problems, we have improved an automatic metal bending machine to solve this problem. Utility Model Content
